Abstract: Epistemic logic is the logic of knowledge and belief. It provides insight into the properties of individual knowers, has provided a means to model complicated scenarios involving groups of knowers and has improved our understanding of the dynamics of inquiry.
Comment: This would be useful in a course on epistemology, formal epistemology, philosophical logic or formal methods in philosophy. This is quite a compact entry for the Stanford Enclyclopedia of Philosophy. It is not hugely technical, but symbol-phobes will find it logic-heavy.
